Subject [jira] [Commented] (CASSANDRA-12705) Add column definition kind to system schema dropped columns
Date Mon, 26 Sep 2016 01:44:20 GMT


Stefania commented on CASSANDRA-12705:

An initial commit is available [here|],
based on the patch for CASSANDRA-12582. The commit adds the column definition kind to {{SchemaKeyspace.DroppedColumns}},
the handling of the schema migration during upgrade is missing.

> Both regular and static columns can currently be dropped by users, but this information
is currently not stored in {{SchemaKeyspace.DroppedColumns}}. As a consequence, {{CFMetadata.getDroppedColumnDefinition}}
returns a regular column and this has caused problems such as CASSANDRA-12582.
> We should add the column kind to {{SchemaKeyspace.DroppedColumns}} so that {{CFMetadata.getDroppedColumnDefinition}}
can create the correct column definition. However, altering schema tables would cause inter-node
communication failures during a rolling upgrade, see CASSANDRA-12236. Therefore we should
wait for a full schema migration when upgrading to the next major version.
